i don't know what to do...
could you give me some advice please?

I got a similar error too. I think it's something related to the architecture of the M1 machines. I thinks fastapi doesn't have a support for the M1 architecture as of now. I think we've to add a feature request then.

By the way if you've found a workaround or a solution, that would help me a lot.

Thanks

In case anyone else stumbles across this with the same issue. Running terminal with Rosetta and reinstalling packages solved this issue for me.

I had a similar problem trying to install dask. I solved it following these steps:

1. Check which version of python are installed (I have : mac os python 2.x and 3.x, anaconda 3.8, brew 3.9):

python -m pipenv.help
Python installations found:

3.9.6: /opt/homebrew/bin/python3
3.9.6: /opt/homebrew/bin/python3.9
3.8.8: /opt/anaconda3/bin/python3
3.8.8: /opt/anaconda3/bin/python3.8
3.8.2: /usr/bin/python3
2.7.16: /usr/bin/python2
2.7.16: /usr/bin/python2.7

2. Use pipenv to create a 3.8 virtual environment:

pipenv install --python '/opt/anaconda3/bin/python3'
pipenv install 'dask[complete]'

Note: by default, pipenv was using the 3.9 brew version of python to create the virtual environment - which caused the problem.

3. Activate the virtual environment and use it:

pipenv shell
